BACKGROUND

With rapid development of wireless communication technology, sharp increase in a number of wireless users, and rapid emergence of High-Definition (HD) multimedia streaming services, there is an increasing shortage of wireless spectral resources. Meanwhile, there is an increasingly high user requirement on a network speed and continuity in network coverage. Expensive finite authorized spectra are failing to meet an increasing wireless demand In order to relieve a pressure on an authorized network, an operator starts to consider meeting said challenges by utilizing an unauthorized frequency band with relatively rich resources.

In related art, in a project (serial number Rel-13) on Long Term Evolution (LTE) network and Wireless Local Area Networks (WLAN) Aggregation (LTE-WLAN Aggregation, LWA for short), the 3rd Generation Partnership Project (3GPP) researches on implementing a dynamic load balance between an LTE network and a WLAN by in-depth fusion of the LTE network and the WLAN at a wireless side through LWA. The 3GPP Rel-13 LWA focuses merely on downlink. With Enhanced LTE-WLAN Aggregations (eLWA), there has been no solution for controlling uplink data transmission to a base station by UE through an LTE network and a WLAN.

DETAILED DESCRIPTION

Exemplary embodiments will be elaborated herein, examples of which are illustrated in the accompanying drawings. In drawing-related description below, unless indicated otherwise, identical references in different drawings represent identical or like elements. Implementations in the following exemplary embodiments do not represent all implementations according to the disclosure. On the contrary, they are merely examples of devices and methods according to some aspects of the disclosure as elaborated in the appended claims.

FIG. 1A is a flowchart of a method 100 for transmitting data according to an exemplary embodiment. FIG. 1B is a schematic diagram of a scene of using the method 100 for transmitting data according to an exemplary embodiment. The method 100 for transmitting data may apply to UE. As shown in FIG. 1A, the method 100 for transmitting data includes steps 101-102 as follows.

In step 101, when a length of cached data of UE is no less than a first preset threshold, the cached data are divided into two groups of data according to a preset mode.

The cached data may be a data packet to be sent to a base station by the UE through an uplink. The data packet to be uploaded by the UE may be cached in a cache of the UE, forming the cached data, when a wireless network where the UE is located is, e.g., heavily loaded. The cache may be a Packet Data Convergence Protocol (PDCP) cache. The length of the cached data generally may not exceed a length of data that can be cached by the cache, i.e., cache capacity.

The first preset threshold may be determined according to a state of a network load of a cell where the UE is located. When the length of the cached data is greater than the first preset threshold, it means that congestion occurs in the wireless network being accessed by the UE. To ensure that the UE may send the cached data to the base station, the cached data may be divided into, e.g., two groups of data according to the preset mode, such as a first group of data and a second group of data. For example, when the cached data are of a length of 12 bits, which is greater than the first preset threshold, e.g., a length of 10 bits, the cached data may be grouped according to the preset mode. The preset mode may be a grouping rule preset between the UE and the base station. The cached data may be grouped in units of bits. In one embodiment, according to the preset mode, a first half of the bits of the cached data are set as the first group of data, and a second half of the bits of the cached data are set as the second group of data. For example, the first 6 bits in the 12 bits may be set as the first group of data, and the second 6 bits may be set as the second group of data.

In step 102, the two groups of data are uploaded to a base station respectively through a mobile network and a wireless local area network (WLAN).

For example, the first group of data and the second group of data may be used respectively to form data packets. The UE may add, respectively in the data packets, identifiers respectively for identifying the first group of data and the second group of data, and position identifiers respectively for identifying positions of the first group of data and the second group of data in all data to be sent by the UE, such that the base station may identify the first group of data and the second group of data according to these identifiers, and may reconstruct the cached data originally generated by the UE using the first group of data and the second group of data according to these identifiers.

In an exemplary scene as shown in FIG. 1B, the mobile network may be an LTE network and the base station may be an evolved Node B (eNB). The scene shown in FIG. 1B may include an eNB 10, UE 20, and a wireless Access Point (AP) 30 of a WLAN. The eNB 10 may cover, e.g., three cells Cell 11, Cell 12, and Cell 13. The UE 20 may be located in the Cell 11. Under a circumstance, the UE 20 may need to transmit data to the eNB 10 through a first link 141 in the LTE network. When the LTE network is heavily loaded in the Cell 11, the UE 20 may cache the data to be transmitted in a cache. To improve efficiency in data transmission by a communication system, it may be detected, according to a technical solution herein, whether the length (such as 12 bits) of the cached data in the cache is greater than the first preset threshold (such as a length of 10 bits). When the length of the cached data is greater than the first preset threshold, the UE 20 may split the cached data into the first 6 bits and the second 6 bits, set the first 6 bits as the first group of data, set the second 6 bits as the second group of data, and then transmit the first 6 bits to the eNB 10 through the first link 141 of the LTE network, and transmit the second 6 bits to the AP 30 through a second link 142 of the WLAN. The AP 30 may then forward the second 6 bits to the eNB 10. When the LTE network is heavily loaded in the Cell 11, the UE is controlled, through the first preset threshold, to transmit data to the eNB 10 through the second link 142 of the WLAN, which effectively relieves a pressure on the first link 141 in data transmission.

The mobile network and the WLAN are communication networks independent of each other. When the mobile network is heavily loaded, with the method 100, the UE is controlled to upload one part of the cached data to the base station through the mobile network and upload another part of the cached data to the base station through the WLAN, such that resources of the mobile network and of the WLAN may be better integrated, improving utilization of the WLAN, greatly relieving a burden of the mobile network in data transmission, improving UE performance in data transmission.

In some embodiments, the method 100 for transmitting data may also include the following steps. When the length of the cached data is less than the first preset threshold, a signal strength of the mobile network and a signal strength of the WLAN may be determined and compared. When the signal strength of the mobile network is no less than the signal strength of the WLAN, the cached data may be transmitted through the mobile network. When the signal strength of the mobile network is less than the signal strength of the WLAN, the cached data may be transmitted through the WLAN.

In some embodiments, the method 100 for transmitting data may also include the following steps. Broadcast signaling sent by the base station may be received. The first preset threshold may be acquired by analyzing the broadcast signaling.

In some embodiments, the method 100 for transmitting data may also include the following steps. Unicast signaling sent by the base station may be received. A second preset threshold may be acquired by analyzing the unicast signaling. The second preset threshold may be less than the first preset threshold. The first preset threshold may be updated with the second preset threshold. The cached data may be stored in a PDCP cache.

Refer to an embodiment below for details in data transmission.

With the method 100, resources of the mobile network and of the WLAN may be better integrated, improving utilization of the WLAN, greatly relieving a burden of the mobile network in data transmission, improving UE performance in data transmission.

FIG. 2 is a flowchart of a method 200 for transmitting data according to an exemplary embodiment. The method 200 may be used with the method 100 (FIG. 1A) where the cached data are of a length less than the first preset threshold. As shown in FIG. 2 , the method 200 may include the following steps.

In step 201, it is determined whether a length of the cached data of UE is no less than the first preset threshold. When the length of the cached data is no less than the first preset threshold, the cached data may be uploaded to the base station according to the flow of the method 100 (FIG. 1A), which will not be repeated here. When the length of the cached data is less than the first preset threshold, step 202 may be executed.

In step 202, when the length of the cached data is less than the first preset threshold, a signal strength of the mobile network and a signal strength of the WLAN may be determined and compared.

In step 203, when the signal strength of the mobile network is no less than the signal strength of the WLAN, the cached data may be transmitted through the mobile network.

In step 204, when the signal strength of the mobile network is less than the signal strength of the WLAN, the cached data may be transmitted through the WLAN.

In the exemplary scene shown in FIG. 1B, if the UE 20 may simultaneously access both the mobile network and the WLAN, before the length of the cached data in the cache of the UE 20 reaches the first preset threshold, for better user experience, a link to be adopted by the UE 20 may be determined according to the strength of the signal of the mobile network and the strength of the signal of the WLAN. For example, when the strength of the signal of the mobile network is no less than the strength of the signal of the WLAN, the cached data may be uploaded to the eNB 10 through the first link 141. When the strength of the network signal of the mobile network is less than the strength of the signal of the WLAN, the cached data may be uploaded to the eNB 10 through the second link 142, such that the UE 20 may transmit the data to the eNB 10 through a better uplink.

The network adopted by the UE is adjusted according to the strength of the signal of the mobile network and the strength of the signal of the WLAN, thereby ensuring that the UE may transmit data through an optimal network, avoiding data accumulation in the cache, effectively improving UE performance in data transmission.

FIG. 3 is a flowchart of a method 300 for transmitting data according to an exemplary embodiment herein. The method 300 may be used with the method 100 (FIG. 1A) for acquiring and updating the first preset threshold. Referring to FIG. 1B and FIG. 3 , the method 300 may include the following steps.

In step 301, broadcast signaling sent by the base station may be received.

In step 302, the first preset threshold may be acquired by analyzing the broadcast signaling.

In steps 301 and 302, the eNB 10 may allocate a first preset threshold to UE (such as the UE 20) in a cell according to a network load in the cell. The first preset threshold may serve as a default threshold for the UE 20. The UE 20 may control, according to the first preset threshold, a transmission mode for transmitting the cached data.

In step 303, unicast signaling sent by the base station may be received.

In step 304, a second preset threshold may be acquired by analyzing the unicast signaling. The second preset threshold may be less than the first preset threshold.

In step 305, the first preset threshold may be updated with the second preset threshold.

In step 303-step 305, when the UE 20 is of a preset user level in the cell, the UE 20 may receive unicast signaling from the eNB 10, resolve the second preset threshold corresponding to the preset user level from the unicast signaling, and update the first preset threshold with the second preset threshold. For example, the first preset threshold may be a length of 8 bits. The eNB 10 may detect that a preset user level of the UE 20 is of a platinum user. A preset threshold corresponding to a platinum user may be of 6 bits. Then, a second preset threshold of 6 bits may be sent to the UE 20. After receiving the second preset threshold, the UE 20 may update a system default threshold from 8 bits to 6 bits corresponding to the UE 20.

The second preset threshold may be resolved from the unicast signaling. As the second preset threshold is less than the first preset threshold, the UE's cached data of a smaller size may be uploaded to the base station using the flow of the method 100 (FIG. 1A), which ensures that the UE of a high user level may upload cached data to the base station as soon as possible, such that users of different levels may enjoy different transmission services in transmitting cached data.

FIG. 4 is a flowchart of a method 400 for transmitting data according to an exemplary embodiment. The method 400 for transmitting data may apply to an eNB. Referring to FIG. 1B and FIG. 4 , the method 400 for transmitting data includes steps 401-403 as follows.

In step 401, a state of a network load of a cell where the UE is located is determined.

The eNB 10 may count a total amount of data transmitted by all UE in the cell (e.g., all UE in Cell 11) through the mobile network, and determine, through the total amount of data, the state of the load the UE in the Cell 11 put on the mobile network. The state of the network load may be: smooth data transmission, congested data transmission, etc., for example.

In step 402, a first preset threshold to be adopted by the UE in the cell is determined according to the state of the network load.

In case of smooth data transmission, a large first preset threshold, such as of 12 bits, may be set, such that the UE 20 may transmit data to the eNB 10 stably through the mobile network, avoiding unnecessary grouping/division of the cached data, improving data transmitting performance of the UE 20.

In step 403, two groups of data uploaded by a UE respectively through a mobile network and a WLAN are received. The UE has divided cached data of the UE into the two groups of data when a length of the cached data is no less than the first preset threshold.

In step 404, a data packet in a same data format as that adopted at the UE side is reconstructed using the two groups of data.

As shown in FIG. 1B, the eNB 10 may receive data packets of a first group of data transmitted through the first link 141 of the mobile network and of a second group of data forwarded by the AP 30 transmitted through the second link 142 of the WLAN, and then identify, from the data packets, the respective identifiers, including identifiers respectively for identifying the first group of data and the second group of data, and position identifiers respectively for identifying positions of the first group of data and the second group of data in all data sent by the UE 20. The eNB 10 may identify the first group of data and the second group of data according to these identifiers, and may reconstruct the cached data originally generated by the UE using the first group of data and the second group of data according to these identifiers.

With the method 400, the UE may be allowed to control a data transmission mode according to the first preset threshold, such that resources of the mobile network and of the WLAN may be better integrated, improving utilization of the WLAN, greatly relieving a burden of the mobile network in data transmission, improving UE performance in data transmission. The two groups of data acquired by grouping, by the UE, cached data may be received respectively through two independent communication networks, i.e., the mobile network and the WLAN. The cached data sent by the UE may be reconstructed/recombined, such that no data may be loss during data processing, greatly relieving a burden of data transmission by the UE through the mobile network, improving user experience.

The method 400 for transmitting data may further include the following steps.

Among all UE in a cell, a UE with a preset user level may be determined. A second preset threshold corresponding to the preset user level may be determined. The second preset threshold may be sent to the UE with the preset user level.

The second preset threshold may be sent to the UE with the preset user level by: including the second preset threshold in unicast signaling; and sending the unicast signaling to the UE with the preset user level. The unicast signaling may include the second preset threshold.

The first preset threshold may be sent to UE in the cell by: including the first preset threshold in broadcast signaling; and sending the broadcast signaling to the UE in the cell.

With the method 400, a UE may control, according to the first preset threshold, a transmission mode for transmitting cached data, thereby better integrating resources of the mobile network and the WLAN.

FIG. 5 is a flowchart of a method 500 for transmitting data according to an exemplary embodiment. The method 500 may be used with the method 100 (FIG. 1A) for updating a first preset threshold. Referring to FIG. 1B and FIG. 5 , the method 500 may include the following steps.

In step 501, a UE with a preset user level among all UE in a cell may be determined.

In step 502, a second preset threshold corresponding to the preset user level may be determined.

In step 503, the second preset threshold may be included in unicast signaling.

In step 504, the second preset threshold may be sent to the UE with the preset user level.

In the exemplary scene shown in FIG. 1B, the eNB 10 may determine that the UE 20 is of a preset user level in a cell, determine a second preset threshold corresponding to the preset user level, and send unicast signaling to the UE 20, such that the UE 20 may resolve the second preset threshold corresponding to the preset user level from the unicast signaling, and update the first preset threshold with the second preset threshold. For example, the first preset threshold may be a length of 8 bits. The eNB 10 may detect that a preset user level of the UE 20 is of a platinum user. A preset threshold corresponding to a platinum user may be of 6 bits. Then, a second preset threshold of 6 bits may be sent to the UE 20. After receiving the second preset threshold, the UE 20 may update a system default threshold from 8 bits to 6 bits corresponding to the UE 20.

A base station may determine a UE with a preset user level among all UE in the cell; determine a second preset threshold corresponding to the preset user level; include the second preset threshold in unicast signaling; and send the unicast signaling to the UE with the preset user level. As the second preset threshold is less than the first preset threshold, the UE's cached data of a smaller size may be uploaded to the base station using the flow of the method 100 (FIG. 1A), which ensures that UE of a high level may upload cached data to the base station as soon as possible, such that users of different levels may enjoy different transmission services in transmitting cached data.
